PointF.operator-(const PointF) method
Applies to: desktop apps only
The PointF::operator- method subtracts the X and Y data members of two PointF objects.
PointF operator-( [in, ref] const PointF &point );
point [in, ref]
Type: const PointF
Reference to a PointF object whose X and Y data members are subtracted from the X and Y data members of this PointF object.
This method returns a PointF object that is the difference of two PointF objects.
This method overloads the subtraction operator for PointF objects. If A, B, and C are PointF objects, the statement C = A - B is equivalent to C = A.operator-(B).
The following example creates two PointF objects, then subtracts the second PointF object from the first PointF object and stores the result in a third PointF object.
PointF point1(40.0f, 10.0f); PointF point2(-20.0f, -30.0f); // Point3 now contains the coordinates (60.0f, 40.0f). PointF point3 = point1 - point2;
